pc-bios/s390-ccw: Move string arrays from bootmap header to .c file

bootmap.h can currently only be included once - otherwise the linker
complains about multiple definitions of the "magic" strings. It's a
bad style to define string arrays in header files, so let's better
move these to the bootmap.c file instead where they are used.
